Re: Underqualified Sensei
Just to be clear, by "lineage holder," I meant explicitly a confirmed transmission back to O-Sensei, originating from O-Sensei, confirmed by O-Sensei.
Whether I am somebody or nobody, if I am a teacher, I can confirm that my student has at least my understanding of what I am teaching. That does not speak to my understanding, though.
When I hear intra-lineage squabbling or criticism within Aikido, I can't help but wonder if a side-effect of knowing that you are "right" doesn't also often - and possibly inadvertently - carry the extension "the other is wrong." I've seen at seminars senior folks of this style critical of that style, and that style critical of this style, joking and mocking. This is transmitted to all in attendance, and it came from (or was allowed by) somewhere up the chain - evidence of an imperfect transmission at best. What can these people ultimately know about aikido?
In the pools of ordinary folks, we're destined to hear one complain that another does not know what he is doing. It's no surprise.
